Definitions

  • the invention relates to a motor vehicle lock used in all types of closure elements of a motor vehicle. These include, in particular, side doors, rear doors, tailgates, trunk lids or engine hoods. Said closure elements can, in principle, also be designed in the manner of sliding doors.
  • the known motor vehicle lock (DE 102 58 645 B4), on which the invention is based, has a motor vehicle lock having the locking elements lock catch and pawl.
  • the lock catch can be moved, in the usual way, into an open position, into a main locking position and into a preliminary locking position.
  • the pawl has the task of holding the lock catch in the two locking positions.
  • the pawl has to be manually lifted in order to release the lock catch.
  • the pawl In the known motor vehicle lock, the pawl is manually lifted when mechanical redundancy is realized. This means that the pawl is normally lifted by means of a motor, and is manually lifted only in an emergency, for example in the event of a power failure.
  • the known motor vehicle lock is also equipped with a lock mechanism which can be switched into different functional states. These functional states are the “unlocked”, “locked”, “anti-theft locked” and “child-safety locked” functional states.
  • the “unlocked” functional state the associated motor vehicle door can be opened by operating the internal door handle and the external door handle.
  • the locked” functional state said door cannot be opened from the outside but can be opened from the inside.
  • anti-theft locked functional state said door cannot be opened either from the outside or from the inside.
  • child-safety locked said door can be opened from the outside but not from the inside.
  • the lock mechanism is equipped with a coupling arrangement in which a coupling pin which is displaceable in one plane interacts with different control slots. Realizing the above coupling function in this way is mechanically complex.
  • the invention is based on the problem of designing and developing the known motor vehicle lock in such a way that the structural design is simplified.
  • the functional element which is critical for realizing the different functional states of the lock mechanism can be adjusted both in the lateral direction and in the vertical direction, in each case substantially perpendicular to its longitudinal extent, in relation to a reference plane. This ensures that the adjustment range of the functional element is not restricted to a single plane, this incidentally allowing a particularly simple refinement of the lock mechanism.
  • a bearing arrangement which is preferably positioned in an end region of the functional element, is associated with the functional element.
  • the bearing arrangement of the functional element comprises a ball socket and a ball which engages with the ball socket.
  • the adjustment range, which is discussed above, of the functional element can be realized in a structurally particularly simple manner in this way.
  • the vertical adjustment of the functional element serves to adjust the lock mechanism into the corresponding functional states, for example the functional states “unlocked” and “locked”.
  • the functional element for realizing functional states of the lock mechanism provides a switchable coupling, with the functional element acting as such in the coupled state so as to transmit force.
  • the vertical adjustment of the functional element is associated with coupling and decoupling and the lateral adjustment of the functional element is associated with operation in the coupled state. This association leads not only to a simple structural refinement but also to a reduction in the amount of installation space required.
  • a control drive is provided with a control shaft on which the associated functional element is supported.
  • This can be realized in a structurally simple manner.
  • the control shaft can have a plurality of control sections which are arranged next to one another and are associated with different functional elements.
  • the functional element can be designed to be resilient, in particular in the form of a resiliently flexible wire or strip, and, in the process, to ensure the adjustability of the functional element in the vertical direction solely by means of a bearing arrangement and in the lateral direction solely by means of the flexibility of the functional element, or to ensure the adjustability of the functional element in the lateral direction solely by means of a bearing arrangement and in the vertical direction solely by means of the flexibility of the functional element.

  • the introduction of the reference plane R serves merely to define firstly the vertical adjustment and secondly the lateral adjustment in this case.
  • the vertical adjustment is associated with a change in the distance between the functional element 3 and the reference plane R.
  • lateral adjustment of the functional element 3 is adjustment of the functional element 3 substantially parallel to the reference plane R. Vertical and lateral adjustments can be superimposed on one another in this case, this leading to corresponding adjustments in directions which are diagonal in relation to the reference plane R.
  • the reference plane R can be oriented largely as desired. However, in a particularly preferred refinement, the reference plane R is oriented substantially parallel to a flat face of the motor vehicle lock. Given a corresponding functional association of vertical adjustment and lateral adjustment, this is structurally advantageous, as explained further below. However, in principle, the reference plane can also be oriented substantially perpendicular to a flat face of the motor vehicle lock.
  • the functional element 3 is preferably a lever-like functional element. This means that the functional element 3 is articulated such that it can pivot in any manner and has a lever arm which then also determines the longitudinal extent of the functional element 3 .
  • the functional element 3 is prestressed into the starting position which is illustrated in FIG. 1 .
  • the prestress preferably leads to the functional element 3 always automatically returning to the starting position.

  • the above-described functional element 3 is coupled to one of the participating adjustment elements 1 , 4 , 5 , preferably to the pawl 1 , the external operating lever 4 or the internal operating lever 5 , in such a way that the functional element 3 prestresses the respective adjustment element 1 , 4 , 5 .
  • This double use of the functional element 3 has been discussed further above in conjunction with a pawl spring, an external operating lever spring or an internal operating lever spring.
  • FIGS. 10 to 13 show a further embodiment of a motor vehicle lock according to the proposal which is, in principle, of similar design to the motor vehicle lock which is illustrated in FIGS. 4 and 5 and in FIGS. 6 to 9 .

  • the functional element 3 is deflected such that the functional element 3 is disengaged from the external operating driver contour 7 and from the internal operating driver contour 8 .
  • Operation of the internal operating lever 5 leads to an adjustment of the functional element 3 into the “unlocked” functional position, as is explained in more detail in conjunction with the override contour 11 b.
  • FIG. 12 shows the “anti-theft locked” functional state, which differs from the “locked” functional state, as explained, in that the control shaft-end override contour 11 b is rotated outside the movement range of the internal operating lever-end override contour 5 b.
  • FIGS. 10 to 13 one special feature can be seen in the way in which the external operating driver contour 7 and the internal operating driver contour 8 are realized.
  • the pawl driver contour 6 , the external operating driver contour 7 and the internal operating driver contour 8 are provided substantially parallel to the pivot axis of the pawl 1 and of the external operating lever 4 and of the internal operating lever 5 respectively.

  • the illustration in FIG. 13 shows the state in which the internal operating lever-end override contour 5 b engages with the control shaft-end override contour 11 b during operation of the internal operating lever 5 .
  • a further special feature of the exemplary embodiment which is illustrated in FIGS. 10 to 13 involves the design of the cam 11 a of the control shaft 11 .
  • This cam 11 a is specifically designed such that stable states are in each case set for the control positions “unlocked”, “locked” and “anti-theft locked” on account of the prestressing of the functional element 3 .
  • the arrangement is designed such that an increased deflection of the functional element 3 has to be “overcome” in each case when the control shaft 11 is adjusted between said control positions.
  • This is realized by the cam 11 a being equipped with corresponding edges 21 , 22 .
  • the prestressing of the functional element 3 together with the design of the cam 11 a cause the control shaft 11 to be held in the respective control position.
  • Adjusting the control shaft 11 by motor is also a special feature in the case of the exemplary embodiment which is illustrated in FIGS. 10 to 13 .
  • the control shaft 11 has a blocking contour 11 c which can be moved into engagement with a blocking element 17 .
  • the control shaft 11 and the blocking element 17 can preferably be adjusted by motor in this case too.

  • the blocking element 17 blocks the control shaft 11 initially in the “locked” control position and, for this purpose, engages with the blocking contour 11 c .
  • the blocking element 17 is moved a short distance into a mouth-like recess in the blocking contour 11 c .
  • the control shaft 11 can then be adjusted in the direction of the “anti-theft locked” control position until the blocking element 17 preferably becomes jammed in the mouth-like recess in the blocking contour 11 c and blocks the further adjustment of the control shaft 11 .
  • the above mouth-like recess also has a further advantage. Specifically, said recess also provides an ejector contour 11 d as explained in conjunction with the exemplary embodiment which is illustrated in FIGS. 8 , 9 , said ejector contour 11 d moving the blocking element 17 into the “locked” blocking position when the control shaft 11 is manually adjusted from the “anti-theft locked” control position ( FIG. 12 ) into the “unlocked” control position ( FIG. 10 ).
  • the override contour 11 b is rotated out of the movement range of the internal operating-end override contour 5 b in the “anti-theft locked” control position in any case. This corresponds substantially to the functional principle of the exemplary embodiments which are illustrated in FIGS. 4 to 9 .
  • the design of the cam 11 a of the control shaft 11 is finally advantageous inasmuch as it has, at the side, an associated shoulder 23 which prevents the functional element 3 from jumping off the cam 11 a at the side.
  • FIGS. 14 and 15 show selected components of a control drive 10 , in particular the control shaft 11 of a motor vehicle lock, which otherwise corresponds to the design which is shown in FIGS. 10 to 13 .
  • the control shaft 11 which is illustrated in FIGS. 14 and 15 also operates, in principle, in the same way as the control shaft 11 which is shown in FIGS. 10 to 13 . Accordingly, said control shaft is equipped with a cam 11 a (only schematically illustrated) for engaging with the functional element 3 .
  • An override contour 11 b and a blocking contour 11 c in the above sense are provided in principle, but are not illustrated here.
  • the internal operating lever 5 is decoupled from the pawl 1 and the external operating lever 4 is coupled to the pawl 1 . Therefore, measures are taken in the lock mechanism 2 to ensure that, in the “child-safety locked” functional state, an unlocking process automatically causes the functional element 3 to change over into the “unlocked/child-safety locked” functional position.
  • the “unlocked/child-safety locked” functional position is preferably situated between the “unlocked” functional position and the “locked” functional position.
  • the “unlocked/child-safety locked” functional position of the functional element 3 is schematically illustrated in FIG. 15 c ).
  • Said figure shows that the external operating driver contour 7 and the internal operating driver contour 8 are designed such that, in this functional position, the functional element 3 is disengaged from the internal operating driver contour 8 and the internal operating lever 5 is decoupled from the pawl 1 , and that the external operating lever 4 is coupled to the pawl 1 by means of the external operating driver contour 7 , the functional element 3 and the pawl driver contour 6 .
  • This selective coupling of the two above driver contours 7 , 8 is realized by the external operating driver contour 7 having a greater height than the internal operating driver contour 8 , as seen in the deflection direction of the functional element 3 . This can be seen in the illustration in FIG. 15 .
  • the driver contours 6 , 7 , 8 are not illustrated in FIG. 14 .

  • a further functional element is provided, specifically an independently adjustable child-safety locking element 20 which can be adjusted between a “child-safety locked” position ( FIG. 15 c )) and a “child-safety unlocked” position ( FIG. 15 a ), b )).
  • This adjustment of the child-safety locking element 20 corresponds to the engagement of the “child-safety locked” and “child-safety unlocked” functional states.
  • the child-safety locking element 20 holds the functional element 3 in the “unlocked/child-safety locked” functional position, which is upstream of the “unlocked” functional position, when the control shaft is adjusted into the “unlocked” control position.
  • the control shaft 11 can be moved into all possible control positions, with the setting of the “unlocked” control position leading to the functional element 3 being held in the upstream “unlocked/child-safety locked” functional position.
  • the functional element 3 When the control shaft 11 is adjusted into the “locked” control position, the functional element 3 is adjusted, in an unchanged manner, into the “locked” functional position if the child-safety locking means is engaged. Operation of the internal operating lever 5 also causes an unlocking process by means of the override contour 11 b . Here, however, the functional element 3 falls back only into the upstream “unlocked/child-safety locked” functional position, so that the pawl 1 cannot be lifted by means of the internal operating lever 5 .
  • the child-safety locking element 20 is designed as a child-safety locking shaft, with the child-safety locking shaft 20 further preferably being oriented along the control shaft axis 12 . This is illustrated in FIGS. 14 and 15 . This leads to a particularly compact arrangement if the child-safety locking shaft 20 is at least partially integrated in the control shaft 11 . Here and preferably, the child-safety locking shaft 20 is even integrated completely in the control shaft 11 , with the child-safety locking shaft 20 being arranged in a cutout 24 in the control shaft 11 .
  • the child-safety locking shaft 20 For the engagement of the child-safety locking shaft 20 with the functional element 3 , it may be advantageous for the child-safety locking shaft 20 to be designed in the manner of a camshaft, specifically in such a way that the associated functional element 3 is supported on the camshaft.
  • the child-safety locking shaft 20 is designed in the manner of a crankshaft, and the associated functional element 3 is supported on the crankshaft 20 .
  • the crankshaft 20 has an engagement section 20 a which can accordingly be moved into engagement with the functional element 3 .
  • the child-safety locking shaft 20 is integrally formed, in particular in the form of a bent wire or the like, this being advantageous in terms of production.
  • the child-safety locking element 20 can, as explained, be moved into the “child-safety locked” position and into the “child-safety unlocked” position.
  • the child-safety locking element 20 has an associated adjustment section 20 b by means of which the child-safety locking element 20 can be adjusted.
  • said adjustment section 20 b is coupled to a child-safety locking switch which is accessible from the end of a side door, or to a child-safety locking drive.
  • the child-safety locking element 20 when in the “child-safety unlocked” position, does not influence the adjustment of the functional element 3 .
  • the functional element 3 can be moved into the “unlocked” functional position ( FIG. 15 a )), into the “locked” functional position ( FIG. 15 b )) and into the “anti-theft locked” functional position (not illustrated). This is not the case when the “child-safety locked” functional state is set, as shown in FIG. 15 c ). In this case, the control shaft 11 is in the “unlocked” control position. However, the functional element 3 does not reach the “unlocked” functional position, but rather is automatically held in the “unlocked/child-safety locked” functional state by the child-safety locking element 20 . The resulting functional behavior has been explained further above.
  • control shaft 11 is preferably produced from a plastic material which has the greatest possible hardness. At the same time, the materials should be selected such that as little friction as possible is produced between the functional element 3 and the control shaft 11 .

  • An additional contour of this kind can be realized, in principle, with a low level of expenditure and with a high degree of compactness.
  • One preferred refinement which can be used within the context of emergency operation involves the functional element 3 being situated in the movement range of an emergency operating lever at all times, specifically independently of the functional position of the functional element 3 .
  • a further teaching which is likewise accorded an independent meaning, claims a motor vehicle lock which, apart from the realization of the adjustability of the functional element 3 , is initially constructed in the same way as the motor vehicle locks described above. Reference may be made to the embodiments above in this respect.

  • Preferred refinements of a functional element 3 of this kind are explained in DE 10 2008 018 500.0 from the same applicant, the content of said document forming part of the subject matter of the present application in this respect.
  • the functional element 3 is mounted in a subregion, in particular an end region, of the functional element 3 by means of a bearing arrangement 3 a , specifically such that the functional element 3 can be adjusted, in relation to the above reference plane R, in the vertical direction or in the lateral direction solely by means of the bearing arrangement 3 a and accordingly in the lateral direction or in the vertical direction solely by resilient bending of the functional element 3 .
